A Study of CO2 Chemisorption Equilibrium and Kinetic Modeling for Dry Sorbents |
| 초록 |
Various kinds of solid sorbents for CO2 capture have been studied for their low regeneration energy compared to aqueous amine-based sorbents. Capture process of dry sorbents can be categorized into two types. One is physisorption which physically captures CO2 on sorbent surfaces and the other is chemisorption which chemically reacts with CO2 while absorbing the CO2. Chemisorption of dry sorbents, however, can not be considered to capture CO2 entirely by chemical reaction. So sorbents which fall into chemisorption criterion also partially possess characteristic of physisorption. As a result, when describing the equilibrium and kinetics of chemisorbing sorbents, a model including attributes of both criterions is needed. To construct the model, experiments at various temperatures using gases of different CO2 partial pressure were conducted. Experimental results were fitted into predicted model and parameters of the model were obtained. After analyzing the results, the model was modified to better describe the capture process of sorbents. Through the model, equilibrium and kinetic behavior of sorbents at wide range of temperature and CO2 concentration could be described. |
